Resumo: Dissimilatory iron reduction (DIR) is an important biogeochemical
process with a strong impact not only on the iron cycle but also on the
biogeochemical cycles of other elements, changing dramatically the
composition of the planet’s sediments and soils.(...)

Resumo: Iron is an essential element in life. It is used in a variety of different processes
in the energetic metabolism of different organisms. Among these bioenergetic
processes is photoferrotrophy, characterized by the utilization of Fe(II) as the
sole electron source for photosynthesis. The metabolic activity of
photoferrotrophs is proposed to have had a relevant role in the formation of
ancient geological structures consisting of Fe(III) minerals, such as the Banded
Iron Formations.(...)
